NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_http2 package and not the mod_http2 package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade.

Only configurations using "SSLEngine optional" to enable TLS upgrades are affected. Users are recommended to upgrade to version 2.4.64, which removes support for TLS upgrade.
